pH (ACIDIC or ALKALINE WATER)

What is pH?

The term pH, despite its widespread use, is seldom understood. By scientific definition, pH is the reciprocal of the hydrogen ion activity in a solution. By layman’s definition, it is the expression of whether water is acidic (<7) or alkaline (>7).

pH is measured on a scale of 0 through 14, with 7 as the obvious mid-point or neutral point. By observing the pH scale, one might conclude that 6.0 is just a "little more acidic" than neutral but consider the scientific definition. Each time you descend one whole number (i.e. 7.0 to 6.0), the acidity of the solution is increased by a factor of 10. Thus, a pH of 4.0 is 1,000 times as acidic as a pH of 7.0. Conversely, a pH of 10.0 is 1,000 times more alkaline than a pH of 7.0.

Though our water’s pH will never be extreme enough to harm us directly, high or low pH can lead to several poor and even dangerous conditions in water. Acidic water can cause corrosion of plumbing, contributing to the presence of iron, copper, manganese, and other harmful minerals in your water. Alkaline (caustic) water can cause
gastrointestinal upset.

A pH of 7.5 is the ideal pH for any household water. RAdata reports the pH of your well
water according to the applicable standard, which is represented as an ‘optimum range’
between 6.5 – 8.5. A level of pH that is lower or higher than that range is recommended to be remediated.

Telltale signs of acidic water include blue/green staining in the bottom of tubs or sinks (if you have copper pipes) and pin-hole leaks.

Do I Have Acidic or Alkaline Water?  

If you suspect a problem and your drinking water comes from a private well, you should have the well water tested.  If you have a pH problem (Acidic or Alkaline Water) or any other contaminant is found, RAdata can install water treatment systems to treat any water problem.

Treatment: Neutralizer (pH below 6.5)

pH treatment is accomplished by neutralizing the water with the use of an automatic neutralizing filter. The filter tank is filled with a blend of calcium and magnesium carbonates (commonly referred to as neutralizing mix) made from naturally occurring minerals, which dissolve into the water, making it less corrosive. An automatic backwashing unit cleans the media bed and prevents compaction of the media, which keeps the system operating efficiently.

The neutralizing mix adjusts the pH of the water in a sacrificial process. The neutralizing mix will eventually be depleted, requiring a refill. Your neutralizing tank will need to be filled with neutralizing mix annually in order to continue to adjust the pH.

Treatment: Anion Exchange (pH over 8.5)

An anion exchanger uses the principle of ion-exchange – in this case, anions – to reduce the pH in raw water by removing alkalinity ions. The equipment contains a "bed" of material known as 'resin' through which the untreated water flows. This unit is very different from a standard “cation” water softener. As water passes through the resin, carbonate, bicarbonate, and sulfate ions are exchanged for chloride ions. This ion-exchange process occurs billions of times during the treatment process.

Weekly automatic regeneration, or recharging, is necessary. To recharge the resin, it must be rinsed with a rich brine solution. This washes out the minerals and replaces them with sodium, so the resin is once again ready to exchange ions. During the regeneration cycle, the unit is also backwashed. Reversing the normal flow of water
also serves to remove any turbidity and sediment, which may have accumulated during the ion-exchange process due to the filtering action of the material. Backwashing also loosens and fluffs up the bed of resin.

Treatment: Anion Exchange (pH over 8.5)

PCC Cartridge (for prior corrosion): 

If you are concerned about prior corrosion, there is a filter cartridge which can be installed in conjunction with pH treatment called a Hexametaphosphate PCC Cartridge (FDA grade). This cartridge releases food-grade hexametaphosphate that forms a protective coating on metal surfaces, safeguarding against acidity/alkalinity, hardness, chloride, and other factors which effect the corrosion of water equipment and pipes. The cartridge will need to be replaced every 6 months to 1 year, depending on water usage.
